Chronic wasting disease (CWD) survey by hunters in Massachusetts in early 2023. Chronic wasting disease (CWD) survey by hunters in Massachusetts in early 2023.
We implemented an online survey questionnaire for adult Massachusetts licensed hunters in December 2022-February 2023 using the Qualtrics survey platform (Qualtrics, Provo, UT). The online survey covers a number of topics related to chronic wasting disease (CWD) such as knowledge, risk perception, management acceptability, hunting behavior, channel use, and trust in different sources. Of...
Long-term monotonic trends in aquifer and regional groundwater metrics in the United States through 2020 Long-term monotonic trends in aquifer and regional groundwater metrics in the United States through 2020
The U.S. Geological Survey (USGS) Water Resources Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand by delivering routine assessments of water supply and demand. A key part of these national assessments is identifying long-term trends in water availability, including groundwater and surface...
Data for the report Evapotranspiration from the Lower Walker River Basin, West-Central Nevada, Water Years 2005–07 Data for the report Evapotranspiration from the Lower Walker River Basin, West-Central Nevada, Water Years 2005–07
This vector data set represents the evapotranspiration (ET) discharge quantification area polygon in the lower Walker River basin.
Particle size distribution of MIS 5a aeolianites across windward islands of the Bahamas (Great Abaco, Eleuthera, San Salvador, and Long Island) (ver. 1.1, May 2025) Particle size distribution of MIS 5a aeolianites across windward islands of the Bahamas (Great Abaco, Eleuthera, San Salvador, and Long Island) (ver. 1.1, May 2025)
Recent Quaternary carbonate island sediment preservation along low-latitude coastal regions, such as in the Bahamas, contain sediment sourced from adjacent marine environments during interglacial intervals. During these interglacial intervals, denoted by odd-numbered Marine Isotope Stages (e.g., MIS 1, 3, 5), sea levels are at a highstand relative to glacial periods (e.g., MIS 2, 4, 6)...
DESIS and PRISMA spectral library of agricultural crops in California's Central Valley in the 2021 Growing Season DESIS and PRISMA spectral library of agricultural crops in California's Central Valley in the 2021 Growing Season
Here we provide Germany’s Deutsches Zentrum fu¨r Luft- und Raumfahrt (DLR) Earth Sensing Imaging Spectrometer (DESIS) and Italy’s ASI’s PRecursore IperSpettrale della Missione Applicativa (PRISMA) Derived Spectral Library of Agricultural Crops for California. It was developed using DESIS and PRISMA hyperspectral data acquired in August 2021 near Fresno, CA. The 4-bin DESIS image has 60...
Digital Representation of Isopach Maps for Selected Geologic Periods from an Atlas Published by Sloss and others (1960) Digital Representation of Isopach Maps for Selected Geologic Periods from an Atlas Published by Sloss and others (1960)
Information of hydrogeologic and geologic importance from the book, "Lithofacies Maps: An Atlas of the United States and Southern Canada" (Sloss and others, 1960) detailing geologic periods, including the Cambrian, Ordovician, Silurian, and Devonian were digitized from scanned maps. Isopach contours were captured and, along with Geologic Map of North America (GMNA) information (Garrity...
Summary of Responses at the 2021 Colorado River Basin Science and Technology Meetings Summary of Responses at the 2021 Colorado River Basin Science and Technology Meetings
In June and July 2021, the Colorado River Basin Actionable and Strategic Integrated Science and Technology (ASIST) pilot team held a series of 12 Science and Technology Collaboration meetings with U.S. Geological Survey science staff to discuss complex integrated science challenges and solutions related to drought in the Colorado River Basin. These meetings were structured to explore...
X-ray diffraction data and estimates of mineral abundances based on Rietveld refinement for mine wastes collected through the USGS Earth Mapping Resources Initiative (ver. 2.0, April 2025) X-ray diffraction data and estimates of mineral abundances based on Rietveld refinement for mine wastes collected through the USGS Earth Mapping Resources Initiative (ver. 2.0, April 2025)
Powder X-ray diffraction (XRD) data and estimates of mineral abundances determined using Rietveld refinement included in this data release were generated as part of the Earth Mapping Resources Initiative (Earth MRI; https://www.usgs.gov/special-topics/earth-mri). Earth MRI is a partnership between the U.S. Geological Survey (USGS) and state geological surveys and was developed by the...
Molecular resources combined with morphology and geography to provide insights into the evolutionary history of a wide-ranging freshwater mussel species complex (Unionida: Quadrula) Molecular resources combined with morphology and geography to provide insights into the evolutionary history of a wide-ranging freshwater mussel species complex (Unionida: Quadrula)
The freshwater mussel Quadrula quadrula of eastern North America occupies several isolated river drainages along the coastal Gulf of Mexico and northward in the Mississippi Basin and Great Lakes. Previous work has documented high morphological and genetic variation across its range but due to paraphyly of mitochondrial barcodes, variants are currently recognized as conspecific. Here we...
Mercury concentrations in amphibian tissues and egg masses, fish tissues and sediment in subarctic, freshwater systems near Churchill, Manitoba, 2015-2019 Mercury concentrations in amphibian tissues and egg masses, fish tissues and sediment in subarctic, freshwater systems near Churchill, Manitoba, 2015-2019
Comma-separated values (.csv) files containing data related to amphibian, fish, and sediment sampling near Churchill, Manitoba between 2015-2019. Data files contain mercury concentrations in amphibian and fish tissues, amphibian egg masses, and sediment, as well as amphibian and fish morphometrics, life stage, site distance to coast and biome where the samples were collected.
